Continuation of applicatioiixserial'No. 328,736, filed0ctober 6, .1919. This application filedJ-uly 9, 1921, ,Serial No.4s3',40s. Renewed October8, 1 9 26.

This invention relates to a portable fasteningimplement for doors, windows, and the. like, and hasfor itsobject the provision of a simple, cheaply manufactured, e560- tive, durable, and non-tamperable device, adapted to be applied either to a door, in addition to or default of .the usual looks or bolts to insure against unauthorized .entryinto, anapartment ordwelling, or to a win]- dow :for ithenpurpose. of locking the sashes. at any .desireddegree of opening. In the one embodiment, the device comprises a toothed shank or bar adapted to be placed between thedoor-ja-mb .and door and having rn eai 1s forengagingza, socket oi thejanib, aethrust ()lf-COIltzIQt member non-rotatively slidable on the shank tabear against the. face if. the door, and. an, operating member .freely slidable and also, rotatable on theshank and coupled to the thrustu 'iei'nber, the operating member being adapted to cooperate with the teeth'of .the shank after the manner of an ordnance nut with its screw, soas to force. the thrust member against the door and .the latter against the stopiof the dooriamb by virtue Oftll purchase secured'by the portion of the shank caught in the jan b. In the-other embodiment of the invention the shank is provided with line-ans tor engage.- ment with the top. of the lower sash and the thrust or contact member is formed so asto be secured on the top of the upper sash, the degree of opening of the sashes being determined'by the .position to which the memb a e s id a ng he shank, nd hetu ning of the operating memberin engagement with the teeth of the shanlcat the desired position serving to @fasten the whole in fixed relation.

A further object of the invention is to provide .aportable fastening device of this general character which will give audible warning by causingna detonation or detonations in event of an attempt to force the door orwindow. To, this end the device may be said to comprise,broadly, relatively movable, cooperativ m rs adapted o engage he door and jamb or er at vely movabl sashes and havin g means for locking them in fixed relation, together with an explosive cartridge or cartridges in one ofthe members, adapted and arrangedto be undisturbed ity n ry lmnip l mi u t be 6. 5 p dedbycess ve ss bet en h members. ln'the ,prferred eonst-ructionof the devicethese cartridges or explosive charges may be loeated in the portion oi the operating ember opposed o the pre u e e which latter will act as a firing element under heavy pressure of blows.

A still further object is to provide an alarm system wherebythe user tell or be informed of an attempt to force entrance into hisroomor domicile through noise-making means forming a part ofthis device.

Further advantages of construction will be brought outin t-he.specification and illustrated in the drawings forming a part thereot, in which drawings r i .Fig. 1 is a top. plan view of the device, showing the same in cooperation with a closed .door and door-jamb', said door and janibbeing shown in section;

' Fig. 13 is a detail of one ofthe elements.

In the drawings, 1 is a flat shank or bar having teeth 2 out along its opposite edges, and provide'l at one end with a beveled-off blade-tip portion 3. Spaced, parallel, opposed ears 1 and 5 are formed near the forward endof the shank 1, said'earsprojecting from one of theffla t sides-of the shank and havingbeveled spur projections 6 on their rearedges. One of said ears may also have a forward cut-out portion 7 to form ahook. The other end of'the shank is desirablyprovided with ear-s8 punched up slightly from one face and projecting toward each other.

Cooperating with the shank is a "barrel rereting membe P e ra ly knurled. on its outer surface, and provided at its ends with internal fian es having circular openings 1 1 formed with partial "helices 10,

and key-hole slots 14 permitting the barrel to be moved straigl'it along the shank. said partial helices being adapted to coact with rel to turn relatively to the contact mem-' her.

In the construction illustrated in Figs.

1 to 10. the contact member is made in such form that its forward portion 16 lies at one side of the shank 1. that is to say the Hat side opposite to that from which the ears eland 5 project. As illustrated it is of approximately U-shaped cross-section, embracing the toothed edges of the shank. with internal loimitudinal. grooves receiving these edges and slide hearing flanges 13 overlyinnthe exposed flat side of the shank adir'reent the barrel.

The operation of the device is as follows: The forward portion of the shank is placed flat against the door-jamb. with the ears entered into the locleplate socket, and their spurs 6 hooked over the edge of the plate era-mine". the members 9 and 11 being suit.- ciently withdrawn so as to permit the door 15 to clear the forward end 16 of the slidine; thrust or contact member. The portion 16 of the Contact member being at the side of the shank away from the ears 1-. hpclears the projection of the door-jamh, as seen in Fig. 1. After placing the device in this uninner. the door is closed. which secures the shank and its ears t and 5 between the door 15 and the door-jamb 16. whereupon the barrel 9 and the member 11 are pushed as close to the door as possible and the barrel is then turned in a nutlike mannergtbe partial helices or spiral cams 10 cooperatinn with the teeth 2 on the sides of the shank to thrust themember 11 tightly against the door. In this waya very eifective fastening is produced. preventing opening of the door.

For the purpose of preventing any tendency of the nut member 9 to jar loose by retation, a circular series of slight depressions 1'? are formed in the end of-the member 9, such depressions cooperating with one or more humps 18 on the member 11.

lVhen using this device as an alarm in conjum-tion avith the fastening feature. sockets 19 may be provided in the forward end of the member 9. for the reception of blankcartridges or explosive charges 20. These cartridges are of such character as not to be exploded by pressure .COllSlClBl'dlfily in excess of that developed in the intended use of the device, but if after the member 9 has been screwed up suliiciently to efl'ec-- tively fasten the door, an attenirpt is made to force the same from the outside, either by pressure being placed thereon or by jimmy-- ing, the excessive force thus applied through the member ll will cause one or more of the blank cartridges to explode, thereby notitying the occupant of the room, ara'l prohably the occlupants of adjoining rooms, that some oneis endeavoring to gain unwarranted. admission. As indicated drawing, the cartridges may be located immediately behind the depressions 18, in which event the humps 18 serve as firing pins. I

As applied to windows, a slight modifica-j member 11 in the door fastening, the other elements being substantially identical, with the exception that the shank 1 is longer and is provided at one of its ends with a turned over portion 22 for grasping the bottom of the upper sash, instead of havingthe ears 4-} 5 of the other form., It will. be perceived that with this device the window can be fastened in any position, that is, either entirely closed or partly opened. Ilhe plate. 2.1 has an opening 23 which slips over the ordinary form of sash-fastener, and is adapted to be held firmly to the top of the upper sash by the locking" arm 24: of such fastener. v

Returning to Figs. 1 to 10 it will be seen that the barrel 9 can be slidto therear end of the shank, whereby a' coin inserted in a slot 25 in the barrel and between and under the ears 8. the member 9 will secure the bar-' rel against relative rotation on the shank and the device may be used as an efficientscrew-driver. y I 10 of the drawings, it will also be seen that by using: the hook 7 the device can be used as a bottle-opener.

I do not wish to limit myself to any particular form illustrated; but various modifications maybe resorted to within the scope of my invention. j

The subject-matter of this application is a continuation of my application filed October 6, 1919. Serial No. 328,736.
